That is a kludgey and dangerous assumption.  It would be better to have an
ELFW macro like ElfW, so you can use "ELFW(R_TYPE) (reloc->r_info)".  It's
probably not a good idea to add a name like ELFW to the public header, even
though ElfW is already there.  So the new macro would go in include/link.h.


Thanks,
